sanidine [′san·ə‚dēn]

(mineralogy)

KAlSi₃O₈An alkali feldspar mineral occurring in clear, glassy crystals embedded in unaltered acid volcanic rocks; a high-temperature, disordered form. Also known as glassy feldspar; ice spar; rhyacolite.

Sanidine

a rock-forming, monoclinic variety of feldspar; it is a solid solution of KAlSi₃O₈ and NaAlSi₃O₈, with the content of the potassium component ranging from 100 to 37 percent and a disordered distribution of Al and Si in the structure. At less than 37 percent KAlSi₃O₈, the structure becomes triclinic (high-temperature albite). In solid solution, sanidine contains up to 5–10 percent CaAl₂Si₂O₈. Sanidine is one of the chief minerals of young extrusive and hypabyssal acid rocks (seeFELDSPAR).
